C9 Investigation of factors affecting the capacitance of a parallel plate capacitor using electrometer

Procedure

A. Relationship between charge and p.d. in capacitor

7. Touch the upper plate with the screened wire of the electrometer to transfer the charge from the parallel plate capacitor to the electrometer. Record the reading of the milliammeter , which represents the charge stored (Q) in the internal capacitor.

9. Repeat steps 6 to 8 with the other values of voltage outputs (V) of the HT supply in steps of 5 V. Tabulate the results.

Graphs of I against t are plotted on Graph 1. The graph of capacitors connected in series shows an exponential decay curve similar to a capacitor alone, but with the values of t approximately halved. The graph of capacitors connected in parallel also shows an exponential decay curve similar to

The battery box contains 4 batteries, which allows us to change the electromotive force (e.m.f.) in our investigations on the relationships between e.m.f. and current. The voltmeter measures the exact potential difference (p.d.) delivered by the batteries. The resistance substitution box allows us to adjust the resistance.

When a dielectric is placed between charged plates, the polarization of the medium produces an electric field opposing the field of the charges on the plate. As the capacitance is inversely proportional to the electric field between the plates, the presence of the dielectric reduces the effective electric field, he capacitance of the parallel plate is increased.

When we compare the Q-t graph with the I-t graph, we can see that their shape are very similar, this can prove that the charge Q remaining in the capacitor at any time is directly proportional to the current I.

is density is radius and g is gravity) You then combine these equations in the format weight=viscous drag+upthrust to obtain the equation mg=6?r?v+ ?r3?g. By measuring all the unknowns bar ? (coefficient of viscosity) I shall be able to rearrange the formula and find the viscosity.

To analyse the graph of ripple voltage against capacitance further, the relationships between the two variables and whether or not the graph shows exponential decay, I have produced two more graphs as measured ripple voltage against calculated ripple voltage and a logarithmic graph.
